GEORGE NUTTALL, OF CHESTER, PENNSYLVANIA.

HEDDLE-FRAME.

To all whom it may concern:

Be it known that I, Gnonen N'UTTALL, a citizen of the United States,residing at Chester, in the county of Delaware, in the State ofPennsylvania, have invented an Improved Heddle-Frame, of which thefollowing is a specification.

My invention relates to heddle frames and consists of a novelconstruction of heddle frame wherein the heddle rods are secured inposition in such a manner that they are always under tension.

It further consists of a novel construction of a heddle frame whereinthe stile or end piece, to which the cross rods are secured, is formedpreferably of an integral piece of material which is deflected in such amanner as to form a chamber, adapted to receive the ends of the crossrods and also the fastening devices whereby the said rods are adjustablysecured in assembled position.

It further consists of a novel construction of stile or end piececonsisting preferably of an integral piece of metal which is bent toform a U-shaped portion, the bottom of which is provided with a slot toreceive the ends of the heddle rods, and wherein a spring is secured tothe stile in such a manner as to be wholly contained within the chamberformed by the outwardly deflected sides, and in such a manner that thesaid spring will exert a yielding pressure on the end of the rods, whichlatter are detachably secured thereto.

It further consists of a novel manner of securing my novel constructionof end stile to the cross rods whereby a very rigid and advantageousconstruction is produced.

It further consists of other features of construction, all as will behereinafter fully set forth.

For the purpose of illustrating my invention I have shown in theaccompanying drawing one form thereof which is at present preferred byme, since the same has been found in practice to give satisfactory andreliable results although it is to be understood that the variousinstrumentalities of which my invention consists can be variouslyarranged and organized and that my invention is not limited to theprecise arrangement and organization of these instrumentalities asherein shown and described.

line so 37, Fig. 3 showing a portion of a heddle frame embodying myinvention. Fig. 2 represents a section on line P-Q, Fig. 1. Fig. 3represents an end elevation of a portion of the heddle frame. Fig. 4trepresents an elevation of the heddle frame partly in section. Fig. 5represents an end view thereof.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings: A and F designate the stiles or end pieces ofmy heddle frame, the same being formed of any snitable material andpreferably U-shaped in order to form a chamber or channel having oneside thereof open and the opposite side from the open side beingprovided with apertures J through which the ends of the heddle rods Cpass, as will be hereinafter described.

The end pieces are formed in any suitable or desired manner and have thestrip E bent therefrom in order to form a connection or connecting piecefor the cross rails B, it being understood that the ends of said crossrails B are suitably connected with the end pieces A and F by means ofthe eXten sions E, in the present instance a portion of the extensionbeing driven into engagement with the cross rails, it being noted thatthe ends of the cross rails do not project beyond the outer edge of theend pieces but are preferably flush therewith, as best understood fromFigs. 1 and 1-. The heddle rods C are provided with hooks K at oppositeends and are adapted to pass through the apertures J in the end piecesin order that the hooks K. at one side of the heddle frame may beengaged with pins L or other suitable means, for detachably holdingthese ends of the heddle rods in proper position with respect to thisend piece F, it being noted that the ends of the heddle rods are seatedwithin the channel or chamber of the end piece F in the presentinstance. The opposite end of the heddle rods pass through the aperturesJ in the end piece A and seated within the channel of said end piece andsuitably secured thereto is a locking spring D which is adapted to beengaged by the hook K of the heddle rods C in order that the said springwill exert a yielding pressure on the ends of the rods and yet hold thesame properly in position.

Attention is called to the fact that the springs and cues of the heddlerods are entirely contained within the chamber or channel. formed by theend piece A.

From the above it will be understood that I have provided a heddle framewhich is rigid in construction; that I provide a suitable tension forthe heddle rods and that I provide the chambers or channels in the endpieces to receive the ends of the cross rods and of the heddle rods inorder that the same may be seated within the channel or chamber so thatthe edges of the end pieces have no projecting portions,-the advantagesof which are evident to those skilled in the art.

Vhat I claim is 1. In a device of the character stated, channeled endpieces, cross rails secured thereto with the ends within the channels, aheddle rod having one end detachably secured to one of said end pieceswithin the channel, and yielding means seated within the channel of theother end piece and adapted to engage with the end of the heddle rod,whereby a tension is exerted upon the latter.

2. In a device of the character stated, channeled end pieces havingapertures therethrough, cross rails secured to said end pieces with theends of said cross rails seated in the channels, a heddle rod having oneend passing through an aperture in one of said end pieces and adapted tobe seated within the channel and engage with said end piece, theopposite end of said heddle rod passing through an aperture in the otherend piece, and yielding means carried by the last mentioned end pieceand seated within the channel and adapted to engage with the end of saidrod within the channel whereby tension is exerted upon said rod.

3. In a device of the character stated, channeled end pieces havingapertures therein, cross rails secured thereto having the ends thereofseated within the channels, pins suitably connected with one of said endpieces adjacent the apertures thereof, heddle rods passing through theapertures of said end piece and engaged with said pins within thechannel, the opposite ends of said heddle rods passing through theapertures of the other end piece and being seated within the channel,and yielding means seated within the channel of the said opposite endpiece and engaging with the ends of the heddle rods for yieldinglyholding the same in proper position.

t. In a heddle frame, the combination of cross pieces and U-shaped endpieces secured thereto, said end pieces having apertures therethrough,heddle rods passing through said apertures and detachably secured at oneend to one of said end pieces within the channel thereof, and springmeans secured within the channel of the other end piece and adapted toengage with the ends of said heddle rods within the channel foryieldingly securing the rods with respect to the frame.

5. In a heddle frame, the combination with channeled end pieces, ofcross rails, said end pieces having strips deflected there- -from andsecured to said cross rails, and said end pieces having apertures atsuitable points, heddle rods adapted to pass through said apertures,means on one of the end pieces for engagement with one end of a heddlerod, and yielding means on the other of said end pieces for engagementwith the other end of the same heddle rod, both of said means beingseated within the channels of said end pieces.

6. In a heddle frame, the combination with U-shaped end pieces havingtheir ends provided with apertures near each end, of cross rails passingthrough said apertures and having their ends flush with the sides of theend pieces, said end pieces having a portion thereof near each endoutwardly deflected, means for securing said outwardly deflectedportions to the cross rails, said end pieces having slots through thebottom thereof, heddle rods adapted to pass through said slots, meanslocated within one of said end pieces for securing one end of the heddlerod thereto, and means secured within the other of said end pieces forsecuring the other end of the heddle rod in position.

7. In a heddle frame, the combination with channeled end pieces, ofcross rails, said cross rails being suitably secured to said end pieces,said end pieces having apertures at suitable points, heddle rods adaptedto pass through said apertures, means on one of the end pieces forengagement with one end of a heddle rod, and yielding means on the otherof said end pieces for engagement with the other end of the same heddlerod, both of said means being seated within the channels of said endpieces.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GEORGE NUITALL.
